RELATED APPLICATION DATA

This application is a Divisional of U.S. patent application Ser. No. 14/294,137 filed Jun. 2, 2014, which claims the benefit of U.S. Provisional Application No. 61/956,067 filed Jun. 1, 2013, both of which applications are incorporated herein by reference in their entirety.

FIELD OF THE DISCLOSED EMBODIMENTS

The present disclosure relates to the application of adhesive sheet materials, and, more particularly, an arc squeegee and method for applying adhesive sheet materials.

BACKGROUND

Adhesive sheet materials are becoming the increasingly popular choice for advertising or otherwise displaying graphics on signs, automobiles, indoor and outdoor walls, indoor and outdoor floors, indoor and outdoor ceilings, buildings, and numerous other surfaces. Adhesive sheet materials typically have a display side bearing desired graphics, colors, texture, images, and/or text, and an application side that is coated with an adhesive substance and allows for application to various surfaces. The adhesive sheet material is typically applied in oversized sections and then cut or shaped to the desired shape and size. The size of the oversized sections and the size of the surface to which the adhesive sheet material is being applied vary greatly depending on the application.

One type of adhesive sheet material, which is commonly used in the vehicle wrap industry is vinyl paint wraps. Although vinyl paint wraps are common, vehicles can be customized using a variety of adhesive sheet materials and the customization can include, but is not limited to including, body color change and/or texture change.

Adhesive sheet materials are applied to surfaces that have a variety of unique features, such as contours, welded obstacles, edges, texture, and elements such as handles or windows. It is desirable to shape the adhesive sheet material around the surfaces' unique features. The adhesive sheet material is best applied once gently heated during the application process, the heat serving both to activate the adhesive and to render the adhesive sheet material more pliable and thus amenable to compliance with the application to the surface and its unique features. Generally, a heat source, such as a propane or other combustible gas torch is used to heat the adhesive sheet material.

Application of adhesive sheet material is a pressure sensitive process. Applying the wrong amount of pressure can result in improper installation of the adhesive sheet material. Difficulties often arise during application of adhesive sheet material to variations in the surface or irregular surface features, such as contours, welded obstacles, edges, texture, and elements such as handles or windows. Issues can arise if too little, too much, or non-uniform pressure is applied when installing the adhesive sheet material to variations in the surface or irregular surface features. These issues include gaps, air bubbles, or air-pockets in-between the surface and the adhesive sheet material and post application lifting of the adhesive sheet material from the surface caused by shrinkage of the adhesive sheet material after being overstretched. If the adhesive sheet material is not properly adhered to the surface, it can result in aesthetic problems, peeling off of the adhesive sheet material, and/or premature delamination from the adhesive sheet material causing future failure.

Currently, the art lacks a reliable and desirable apparatus and method for flawlessly applying adhesive sheet material to variations in the surface or irregular surface features, applying the correct pressure, and preventing gaps, air bubbles, air-pockets, and lifting between the surface and the adhesive sheet material.

Accordingly, there is a need for a device and a method to facilitate the positioning, affixing, applied pressure, user exertion, and smoothing of the adhesive sheet material to the desired surface.

BRIEF SUMMARY

The present disclosure fills the need for a device and method that facilitates and addresses the shortcomings of the current devices and methods for applying sections of adhesive sheet material to variations in the surface or irregular surface features and preventing gaps, air bubbles, air-pockets, and lifting between the surface and the adhesive sheet material.

According to one aspect of the present disclosure, a method of using an adhesive sheet material application squeegee is disclosed. The method comprises securing a portion of adhesive sheet material to a surface and applying the adhesive sheet material to the surface with the adhesive sheet material application squeegee.

The method comprises providing an adhesive sheet material application squeegee having at least one convex arc edge, securing a portion of adhesive sheet material to a surface, and applying a desired pressure with the at least one convex arc edge of the adhesive sheet material application squeegee to the adhesive sheet material to secure the adhesive sheet material to the surface.

According to another aspect of the present disclosure, a method of applying adhesive sheet material is disclosed. The method comprises providing an adhesive sheet material application squeegee having a first edge and at least one convex arc edge, providing an adhesive sheet material, securing a portion of adhesive sheet material to a surface, and applying a desired pressure with the first edge and the at least one convex arc edge along the adhesive sheet material to secure the adhesive sheet material to the surface.
